How can I present text?
The most common way to show text is using a sketchpad or feedback item. These allow you to enter text and other visual stimuli. For a questionnaire-like way to show text, you can use forms.
Note: The text_display plugin has been removed as of OpenSesame 3.0.0, because it was outdated and did not provide any functionality that is not offered by forms and sketchpad items.
You can use a HTML tags, which you can simply insert into your text. You can use these tags everywhere: In sketchpad items, in inline_scripts (provided you use the
Canvas class), in forms, etc.
style directly as keywords in a
<span> tag no longer works. This was invalid HTML, and has been deprecated as of OpenSesame 3.2. The example below shows the correct way to change the family (style), size, and color of text.
OpenSesame supports a sub-set of HTML tags: - <b>Bold face</b> - <i>Italic</i> - <u>Underline</u> In addition, you can pass 'color', 'size', and 'style' as keywords to a 'span' tag: - <span style='color:red;'>Color</span> - <span style='font-size:32;'>Font size</span> - <span style='font-family:serif;'>Font style</span> Finally, you can force newlines with the 'br' tag: Line 1<br>Line 2
Variables and inline Python
You can embed variables in text using the
[...] syntax. For example, the following:
The subject number is [subject_nr]
... might evaluate to (for subject 1):
The subject number is 1
You can embed Python code using the
[=...] syntax. For example, the following:
The subject number modulo five is [=var.subject_nr % 5]
... might evaluate to (for subject 7)
The subject number modulo five is 2
You can select one of the default fonts from the font-selection dialogs (Figure 1). These fonts are included with OpenSesame and your experiment will therefore be fully portable when you use them.
The fonts have been renamed for clarity, but correspond to the following open-source fonts:
|Name in OpenSesame||Actual font|
||Droid Sans Mono|
||WenQuanYi Micro Hei|
||Droid Arabic Naskh|
||Droid Sans Hebrew|
Selecting a custom font through the font-selection dialog
If you select 'other ...' in the font selection dialog, you can select any font that is available on your operating system. If you do this, your experiment is no longer fully portable, and will require that the selected font is installed on the system that you run your experiment on.
Placing a custom font in the file pool
Another way to use a custom font is to put a font file in the file pool. For example, if you place the font file
inconsolata.ttf in the file pool, you can use this font in a sketchpad item, like so:
draw textline 0.0 0.0 "This will be inconsolata" font_family="inconsolata"
Note that the font file must be a truetype
